I am building a Primo using a SKR pro v1.2 board with a touch screen
I hooked the power, touch screen, the steppers and small fans to function test.
Stepper X1 Y1 and Z1 as well as Fan0 all work and respond to touch screen commands
X2 and Y2 not responding nor is fan1 or fan2
What steps should i take to Trouble shot this?
